- Avg. Household :
- electricity 3500 kWh/yr
- gas 1500 m3/yr, 15000 kWh/yr
- gasoline 2000 ltr/yr, 20000 kWh/yr - total: 38500 kWh/yr
- Solar panels on a “dutch roof” app. 3000 kWh/jr - More than 12 roofs needed!

- Total consumption incl.
- food, products, transport, travelling - AVG household:

Annual Dutch natural gas production: 85 BCM This can generate (by gas fired plants) as much electricity as 30,000 off shore wind turbines
(5 MW each)
Converted: Currently The Netherlands has approx. 250 of these turbines
85 BCM natural gas
… is equivalent to the amount of energy the sun will give in 18s on the globe or a week in the
Netherlands
But it still need to be converted to usable energy and energy that can be stored
